Carbon nanotube (CNTs) are known to have high mechanical strength and electrical conductivity, and low density. Although CNTs have outstanding properties, CNT fibers (CNTFs) have not yet reached that level. To enhance mechanical properties of CNTFs, a few parameters including CNT length, aspect ratio, alignment, densification, and cross-linking should be considered and optimized. One promising approach to enhance mechanical properties may polymer-infiltration and the introduction of cross-linking bonds between adjacent carbon shells. Herein, I will present an effective method to make high-strength CNTFs through thermal treatment and cross-linking. The CNTFs produced by liquid crystalline spinning process were also introduced in terms of mechanical and electricla properties. |
